Grand Caravan FWD V6-3.3L VIN R (1999)
5. Install the required fitting from Pressure Test Fittings, Special Tool 6833 into the inlet port of the proportioning valve assembly, from which the
chassis brake line was removed. Install the removed chassis brake line into the Pressure Test Fitting. Install the required fitting from Pressure Test
Fittings, Special Tool 6833 into the required outlet port of the proportioning valve. Install the required fitting from Pressure Test Fittings, Special
Tool 6833 into the required outlet port of the proportioning valve. Then install the removed chassis brake line into the Pressure Test Fitting.
Pressure Gauges Installed On Pressure Test Fittings
6. Install a pressure gauge from Gauge Set, Special Tool C-4007-A into each pressure test fitting. Bleed air out of hose from pressure test fittings to
pressure gauges, at the pressure gauges. Then bleed air out of the brake line being tested, at that rear wheel cylinder.
7. With the aid of a helper, apply pressure to the brake pedal until a pressure of 6895 kPa (1000 psi) is obtained on the proportioning valve inlet
gauge. Then based on the type of brake system the vehicle is equipped with and the pressure specification shown on the following table, compare
the pressure reading on the outlet gauge to the specification. If outlet pressure at the proportioning valve is not within specification when required
inlet pressure is obtained, replace the proportioning valve.
8. Repeat steps 2 through 7 for the other proportioning valve of the assembly.
CAUTION: When mounting the original or a replacement proportion valve on the frame rail of the vehicle install the mounting bolts in only the
two forward holes of the mounting bracket. Proportioning valve split point pressure conversion is 1 bar is equal to 14.5 psi.
